BUTTONHOLE-SHEARS.

SPECIFIOATIOllT forming part of Letters Patent N0. 726,156, dated April 21, 1903. Application filed-April 26, 1902. Serial No. 104,839. N0 modeld T0 all whont it may concern.-

Be it known that I, CHARLES E. GOLDSMITH,

a citizen of the United States, and-a resident of Waterbury, in the county of New Haven and State of Connecticut, have made a certain new and useful Invention in Buttonhole- Shears; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art towhich it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of my shears open completely. Fig. 2 is a similar view closed. Fig.3 is a side elevation of the shears partly open and taken from the opposite side. Fig. 4 is an end elevation of the shears.

The invention has relation to combined shears and buttonhole-cutters; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating this invention, the letter a designates one branch of the shears, and?) the other branch, these branches being provided with the usual bows for the thumb and finger, The blade of the branch 01, has a long shear edge terminating near the rivetc'in a pointed shoulder 67, back of which the blade is indented or cut away transversely justin front of the rivet portion, as indicated at e. The blade of the branch I) also has a long shear edge terminating in a pointed shoulder f, said shoulder extending at right angles, or nearly so, to the shear edge and forming atransverse slot or indentation g in the blade of a depth about equal to the breadth of the blade at the shoulder, this deep slot being provided for by an increase in the width of the blade, usually in the form of a bow h, where it joins the rivet portion just in front of which such slot is located, as in the case of the indentation of the branch a, which is more shallow than the indentation of the branch I). The rivet por-.-

tion of this blade is extended opposite to said pointed shoulder to fornra guard-bearing lug K, which is directly opposite the point of such shoulder and which is in the plane thereof, bearing on the inner face of the blade a. By means of this bracing-lug extension, which partly closes the notch or indentation of the blade, this portion of the blade b is not only materially'strengthened and fortified against torsional action, but also is provided with a guide-bearing, whereby the shoulder-point of the blade at is kept from striking against the shoulder-point of the blade I) when the scisthe bows from the rivet, these points do not in the ordinary use of the instrument for shearing cloth become disconnected. In order to separate the blades for buttonhole-cutting, there must be some extra separation of the bows by the thumb and finger, which is It will also easily appreciated in practice. be seen that the shoulder-points beingbrought nearer the rivet are provided with greater leverage in penetrating the cloth and are more firmly braced against the crowding action of the material, which has a tendency to spring the blades apart, and thus prevent the cutting action when the shoulder-points are far from the rivet.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. The combined shears and buttonhole-cutter, one blade of which has. a swelled or enlarged portion near the rivet, and is provided with a deep cut-away portion or notch in said enlargement forthe reception of the edge of the cloth, said notch having its greatest extent transversely'of the blade, one side of said notch meeting the cutting edge of the blade to form a point, and the guard-lug of said blade opposite said point and partly closhaving also a notch or cut-away portion, substantially as specified. I

2. The cornbinedshears and buttonhole-cutter, having the notches in the blades thereof, and the guard-lug extension of one of said 'ing the notch, the -other blade of the shears blades, and opposite the point formed where the cutting edge of the blade meets the edge of the notch, said lug extension partly closing the notch of the blade, substantially as specified.

3. The combined shears and buttonhole-cutter, one of the blades of which has a deep indentation or notch for the reception of the cloth, and having its greatest extent transversely of the blade, and the other blade of which has a more shallow indentation or notch, substantially as specified. V

4. Thecombined shearsand buttonhole-cutter, comprising a blade having, a pointed shoulder near the rivet, and a blade having also a pointed shoulder near the rivet, a transverse indentation back of its shoulder, and
